Liquid dispenser



Oct. 31, 1933. N. TAYLOR LIQUID DISPENSER Filed Jui 1s 1932 ATT'QQN Patented Oct. 31, 1933 UNITED STATES PATENT OFFICE 15 Claims.

This invention relates to liquid dispensing devices and has for its principal object the provision of means for maintaining a liquid charged with gas during its storage in an opened container and means for utilizing the pressure of the gas in the container to expel the liquid from the container.

Another object is to provide an apparatus wherein, by simple manual movements, a sealed bottle containing a liquid charged with gas may have its seal broken and the liquid may be ex-. pelled from the bottle by the pressure of the gas in greater or less volume at will.

A further object is to provide a liquid dis penser wherein a sealed bottle containing a gas charged liquid may be readily and completely emptied of said liquid without spilling the same.

Further objects will become apparent as my invention hereinafter becomes more fully disclosed.

Referring to the drawing:

Fig. 1 is a vertical sectional view of my invention holding a bottle filled with a gas charged liquid in operative position to discharge the liquid.

Fig. 2 is a vertical sectional view of the apparatus of Fig. 1 in inoperative position.

Fig. 3 is a view, partly in section, along the lines 3-3 of Fig. 2.

Fig. 4 is a sectional view along the lines 4-4 of Fig. 2, and Fig. 5 is a view in elevation of a cutter.

Apparatus for the above objects comprises a base 10 of metal made relatively heavy to offsetthe weight of a bottle 11 supported thereby, said bottle being initially filled with a gas charged liquid 12.

Base 10 may be a casting of circular, square, rectangular or other desired shape and contains a passage 13 for the withdrawal of liquid from bottle 11 through mechanism hereinafter described, one end of passage 13 being tightly connected with a pipe 14 having a downwardly extending discharge 15 thereon.

The entry end of passage 13 terminates in a threaded boss 16 adapted to receive the threaded end 17 of a bottle holder 18; said bottle holder including a body 19 into which a resilient portion 20 is fitted and adapted to fit a bottle neck, a cutter 21 supported centrally of body 19 and having a central passage 22 therein,

spring means 23 adapted to be held in slots 24 cut in body 19 for holding bottle 11 in operative position, and a rubber gasket or seal 25 adapted to be compressed between the bottle 11 and the interior bottom of body 19.

Portion 17 is bored at 26 toreceive the reduced end of cutter 21, which is preferably made of stainless steel having a hardened cutting point, by a drive fit, said bore 26 and passage 22 forming a continuation of passage 13 whereby liquid may be withdrawn at will from bottle 11 and said bore 26 being normally closed by a valve 27 fixed in base 10 and adapted to seat on a valve seat 28 on the lower end of portion 17.

Bottle 11 may be any of the usual bottles adapted to contain ginger ale, mineral water, or other gas charged liquid and is sealed with the well known crimped metal cap 29 which is usu- 7 ally lined with cork 30, or other material, to form a resilient seat for bottle 11 whereby, when the crimped portion of cap 29 is forced over the flanged end of bottle 11, a perfect seal is eflected.

In operation, bottle 11 is upended and, by. a single downward movement, is forced through the resilient portion 20 and past springs 23.

This movement causes cutter 21 to pierce both the cap 29 and the cork 30 androll them back. At substantially the same time the outer face of cap 29 comes in contact with rubber gasket 25 to form a perfect seal by compressing the same, whereby no liquid can escape from bottle 11 except as desired, -it being understood as before stated that valve 27 is in its normal position closing passage 26.

Bottle 11 is then held in operative position in holder 18 by reason of the crimped edge of cap 29 being held under springs 23. when cap 29 is forced past said springs, it being understood that springs 23 are preferably made of circular material to better coact with the rounded edge of cap 29 and thus facilitate the passage of cap 29 therethrough.

When bottle 11 is thus firmly held in operative position to withdraw liquid therefrom, the bottle is simply given a part turn to open passage 26 to passage 13 a desired amount whereupon the gas in bottle 11, which normally will collect therein when full at the upper end or about the level A-A, will force the underlying liquid out through pipe 14 into a receptacle held thereunder.

After a desired amount of liquid has thus been withdrawn, bottle 11 is given a reverse turn to firmly seat valve 27 and close passage 26, whereupon the flow of liquid discontinues.

By a repetition of such steps, or by a, single discharge, bottle 11 will be completely emptied, inasmuch as there is always sufiicient gas pressure available 'in bottle 11 to discharge the liquid therein and thereupon when it is desired to remove bottle 11 and replace with a filled one, the springs 23 are expanded by compressing their ends and permitting the crimpe'd edge of cap 29 to pass therethrough whereupon bottle 29 is simply lifted out of holder 18.

Cutter 21 may be of triangular, circular, or other suitable shape in cross-section, its cutting face being made at an angle to its longitudinal axis to the end that, when the point of cutter 21 pierces cap 29, its following cutting edges cut cap 29 in such fashion that the cut portion of cap 29 is held in close engagement with the cutting face of cutter 21 until cap 29 is sealed by gasket 25. In this fashion it is arranged that the quick downward movement necessary to pierce cap 29 and lock bottle 11 in holder 18 permits substantially no leakage of liquid from bottle 11. If such should inadvertently occur, drainage holes 31 are provided to catch the liquid in base 10.

The resilient portion 20 may be formed in many ways, and body 19 may be integral with portion 20 provided that spring sections 32 are cut and arranged to encircle, guide and hold the neck of bottle 11. It is also to be understood that the threaded parts of 16 and 17 mesh somewhat loosely so that valve 27 will always find a perfect seat.

The advantages gained by the construction and operation described are many. Liquid is always maintained charged due to there being no loss of gas.

A bottle may be partly used and the remainder.

kept fresh indefinitely. Instead of opening a plurality of small pint bottles, for instance, a quart bottle or larger may be used, thus effecting a large saving in the cost of containers.
